To compare changes in the amount and distribution of dental plaque associated with placement of elastomeric modules over a self-ligating bracket during orthodontic treatment and to relate these changes to the periodontal inflammation.
A cross-arch randomization trial was carried out at Bristol Dental School, United Kingdom. Clinical measurements of periodontal inflammation and plaque accumulation and microbiological test were done on 24 patients aged 11-14 years [Mean (SD) age = 12.6 (1.01) years] wearing fixed appliances (Damon 2 brackets, Ormco, Orange, CA, USA) at the start and 3 months into fixed orthodontic treatment.
In the first 3 months of treatment there was no statistically significant difference in bleeding on probing between incisors with and without elastomeric modules (P = 0.125 and 0.508, respectively). The difference in plaque accumulation was not statistically significant (P = 0.78). The difference in probing depths between the incisors was not statistically significant (P = 0.84). The microbiological analysis showed no difference.
Based on this preliminary 3 months study, elastomeric modules were not significantly associated with any increased risk during treatment when compared to self-ligating brackets. The longer term studies are needed to further confirm the findings of the present study.
比较正畸治疗期间在自锁托槽上放置弹性模块前后牙菌斑数量和分布的变化，并将这些变化与牙周炎症相关联。
在英国布里斯托尔牙科学院进行了一项跨牙弓随机试验。对24名年龄在11 - 14岁[平均（标准差）年龄 = 12.6（1.01）岁]的患者进行了牙周炎症、菌斑堆积的临床测量以及微生物检测，这些患者在固定正畸治疗开始时和治疗3个月时佩戴固定矫治器（美国加利福尼亚州奥兰治奥美科公司的Damon 2托槽）。
在治疗的前3个月，有弹性模块和无弹性模块的切牙在探诊出血方面无统计学显著差异（分别为P = 0.125和0.508）。菌斑堆积的差异无统计学意义（P = 0.78）。切牙之间的探诊深度差异无统计学意义（P = 0.84）。微生物分析显示无差异。
基于这项初步的3个月研究，与自锁托槽相比，弹性模块在治疗期间未显著增加任何风险。需要进行长期研究以进一步证实本研究的结果。
